Abstract

Embodiments of the present disclosure relate to a light emitting display panel and a light emitting display device including the same. Specifically, the light-emitting display panel includes: a first light-emitting region, a second light-emitting region, and a third light-emitting region spaced apart from each other and emitting light of different colors; and a photochromic layer surrounding each of the first light emitting region, the second light emitting region, and the third light emitting region and disposed in the non-light emitting region. When the first light-emitting area, the second light-emitting area and the third light-emitting area emit light, the photochromic layer is in a transparent state. The photochromic layer is in an opaque state when light of a wavelength band shorter than visible light is incident on the photochromic layer. Accordingly, it is possible to provide a light-emitting display panel having excellent FOV characteristics and a light-emitting display device including the same.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority from Korean Patent Application No. 10-2020-0156408 filed on November 20, 2020, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Embodiments of the present disclosure relate to a light-emitting display panel and a light-emitting display device including the light-emitting display panel, and in particular, to an organic light-emitting display panel and an organic light-emitting display device including the organic light-emitting display panel. Background technique [0004] Display devices are output devices for presenting visual information and play a key role in the information age. Display devices are being developed to achieve higher performance while being slimmer, lighter and more portable. Among flat panel displays that are much lighter and smaller than cathode ray tubes (CRTs), organic light emitting display (OLED) de...
